England Application September 25, 1939, Serial N0. 296,456 In Great Britain March 13, 1939 4 Claims.

This invention relates to protective arrangements for radiators and consists in providing a combination of one or more pairs of radiators, each pair of radiators being arranged along the 5 walls of a passage for air, armour plating at the entrance to the passage for air, a cap of soft material at the opposite end to the entrance of said passage for air and for closing the space between the radiators, and header tanks protected by the armour plating.

Referring to the accompanying drawing:

Fig. 1 shows a front view of part of an aerofoil with two inlet passages for air;

Fig. 2 is an enlarged sectional View on the line a, a, Fig. 1;

Fig. 3 is a still further enlarged section of a modified construction to that shown in Fig. 2.

Throughout the views similar parts are marked with correspondingletters of reference.

In carrying the invention into effect and as shown in Fig. 1 by a part of the front of an aerofoil, a passage for air to radiators is provided at b along the front edge of the aerofoil. These passages can as easily be carried on other parts of the aeroplane such as the fuselage. Fig. 2 shows a cross section on the line a, a of Fig. 1 and it will be seen that the passage b for air leads to two radiators c and d mounted in the walls of the passage b. Four header tanks are shown at e, f, g, h, for their usual operations in connection with the radiators c and d. The space between the ends of the radiators c and d opposite to the entrance passage b is closed by a cap of soft material as shown at i.

In alternative constructions as shown in Fig. 3 the radiators c and d are kept parallel to each other instead of inclined as shown in Fig, 1 and local adjustments of the Various parts are made accordingly.

By mounting radiators in this fashion bullets aimed at the radiator will pass down the passage for air and out through the cap i instead of passing through the radiator and putting the engine out of action.

The reason that the cap i is made of soft material is to prevent it from being smashed to (Cl. Sil- 36) pieces when hit by a bullet. Soft material Will simply allow each bullet to make a small hole which will have practically no elect on the operation of the radiators. The entrance to the passage for air is armoured by plating 1' for .5 strengthening the entrance and providing extra protection for the header tanks and radiators.

We claim:

1. A body having an air passage through the same, a pair of radiators having front and rear header tanks, spaced apart and inclined at an angle to each other and disposed in' said air passage, armour plating at the entrance of said air passage and extending to the front ends of said radiators to protect the front header tanks, and a cap of soft material for closing the space between the rear header tanks.

2. A body having an air passage through the same, a pair of radiators spaced apart and disposed in said air passage and having front and rear header tanks, armour plating at the entrance of said air passage and extending to the front ends of said radiators to protect the front header tanks, and a cap of soft material for closing the space between the rear header tanks.

3. A body having an air passage through the same, a pair of radiators spaced apart in parallel relationship to each other and disposed in said air passage and having front and rear header tanks, armour plating at the entrance of said air passage and extending to the front ends of said radiators to protect the front header tanks, and a cap of soft material for closing the space between the rear header tanks.

4. In combination with an air foil having a walled air duct through the same, a pair of radiators comprised of front and rear headers connected by tubing, armour plating at the entrance of said duct and extending inwardly to said front headers to protect same from missils that may enter said duct, and a cap of soft material over the inner headers for closing the space between the inner ends of the radiators.
